<h4>Description</h4>

This method is called internally when user selects search field from global searches drop down field.
<div style="height: 10px"></div>

If you have grid defined in the following way:
<textarea class="javascript">
let grid = new w2grid({
    name: 'grid',
    show: {
    	header  : true,
    	toolbar : true
    },
    columns: [
        { field: 'recid', text: 'ID', size: '50px' },
        { field: 'lname', text: 'Last Name', size: '30%', searchable: true },
        { field: 'fname', text: 'First Name', size: '30%', searchable: true },
        { field: 'email', text: 'Email', size: '40%', searchable: true },
        { field: 'sdate', text: 'Start Date', size: '120px', searchable: true },
        { field: 'sdate', text: 'End Date', size: '120px', searchable: true }
    ]
});
</textarea>

And if you change columns directly, you will need to:
<textarea class="javascript">
grid.initAllField('fname');
</textarea>
